Notes
  • Significance: The transmission line played an integral role in the growth of Montana's electrical and mining industries in the first half of the twentieth century. Its construction enabled the transmission of hydroelectricity generated at the Morony Hydroelectric Facility into The Montana Power Company's vast power network. Montana Power's electrical supply, in turn, fueled the unprecedented growth of Montana's zinc industry and aided the company to maintain its prominent status as the state's largest electric utility. The Morony-to-Rainbow Line additionally is a well-preserved example of high-voltage transmission technologies of the early twentieth century.
